Never use this product as a sensing device for personnel protection.
In case of using sensing devices for personnel protection, use products which meet laws and standards, such as
OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.
In case this sensor is used within Japan, SI unit must be used since use of pressure units in Japan is restricted to SI units.

CAUTIONS
DP2 series is designed for use with non-corrosive gas.
It cannot be used for liquid or corrosive gas.
This product has been developed / produced for indus-
trial use only.
Use within the rated pressure range.
Do not apply pressure exceeding the pressure with-
standability value. The diaphragm will get damaged
and correct operation shall not be maintained.
Make sure to carry out the wiring in the power supply
off condition.
Take care that wrong wiring will damage the sensor.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regu-
lator, ensure that the frame ground (F.G.) terminal of
the power supply is connected to an actual ground.
In case noise generating equipment (switching regula-
tor, inverter motor, etc.) is used in the vicinity of this
sensor, connect the frame ground (F.G.) terminal of
the equipment to an actual ground
Thank you very much for purchasing Panasinic products.
Read this Instruction Manual carefully and thoroughly for
the correct and optimum use of this product. Kindly keep
this manual in a convenient place for quick reference.

0.15mm 5-core oil resistant cabtyre cable, 2m long (IP67 type: 5m long)
Do not use during the initial transient time (0.5 sec.)
after the power supply is switched on.
Do not run the wires together with high-voltage lines or
power lines or put them in the same raceway. This can
cause malfunction due to induction.
Avoid use of standard type, flat type and light weight type
of sensor in places where steam and dust is excessive.
Take care that the sensor does not come in contact
with water, oil, grease, or organic solvents, such as,
thinner, etc.
Do not insert wires, etc, into the pressure port. The di-
aphragm will get damaged and correct operation shall
not be maintained.
Do not operate the keys with pointed or sharp objects.
Make sure that stress by forcible bend or pulling is not
applied directly to the sensor cable joint.
Extension up to total 100m is possible with 0.3mm
more, cable. However, in case of using this product as
a CE conformity product, the power wire connected to
this product must be within 10m.

SETTING OF PRESSURE LEAD
DIRECTION AND PIPING
Standard type
Setting of pressure lead direction
The pressure lead di-
rection can be changed
by dismantling
pressure port attach-
ment and changing the
mounting direction. The
tightening torque of the
hexagon-socket-head
bolt (length 9mm or
less) should
0.29N m or less.
Note: Please make sure to close any unused pressure port with
the hexagon-socket-head plug supplied as accessory.
Piping
IP67
When connecting a hexa-
DP2-62
gon-socket-head plug or
DP2-62N
coupling to the pressure
DP2-62E
port, hold the hexagonal
part of the pressure port
with a 12mm spanner
and make sure that the
tightening torque is 9.8N m or less. Also, in order to
prevent any leakage, wind a sealing tape on the cou-
pling when connecting.
However, sealing tape is not required for North Ameri-
can type using NPTF

quired if NPT coupling is used.)
Flat type, Light weight type
Setting of pressure lead direction
The pressure lead direction can be changed by dismantling
the pressure port attachment and changing the mounting
direction. The tightening torque of the hexagon-socket-
head bolt (length 9mm or less) should be 0.29N m or less.
Pressure port attachment
Main body
Piping
When connecting a coupling
to the pressure port, hold the
pressure port attachment
with a 16mm (Light weight
type: 10mm) spanner and
make sure that the tighten-
ing torque is 9.8N m or less
(Light weight type: 1.47N m
or less). Also, in order to prevent any leakage, wind a
sealing tape on the coupling when connecting.
IP67 type
Piping for pressure measurement inlet port
When connecting a coupling to the pressure measurement
inlet port, hold the pressure port attachment with a spanner
and make sure that the tightening torque is 9.8N m or less.
Also, in order to prevent any leakage, wind a sealing
tape on the coupling when connecting.
Piping for atmospheric pressure inlet port
If there is a possibility of
water entering into the
sensor enclosure through
the atmospheric pressure
inlet port, connect a tube
to the atmospheric pres-
sure inlet port through a
M5 coupling and extend
the other end of the tube
to a safe place. In this
case, ensure that this
end of the tube does not
get clogged.
Fitting of front cover
Insert the bosses on the front cover into the guide
holes at the bottom of the pressure port attachment,
and push in the
2
, or direction of the
arrow to fit the
hook.
When removing
the front cover,
release the hook
first.
